A study has been made of the spectra of the Raman scattering of light by germanium microscopic crystals dispersed in a transparent dielectric matrix of germanium dioxide. The results yield the first observation, in the Raman spectra of microscopic semiconductor crystals, of a low-frequency peak due to natural acoustic vibrations of the crystals.
